Abstract

Objectives: to evaluate clinical characteristics, echocardiography parameters in atrial fibrillation patients who underwent radiofrequency ablation. Subjects and methods: A cross-sectional study was carried on 34 atrial fibrillation patients undergoing radiofrequency ablation at 108 Military Central Hospital from 3/2019 to 10/2021. All clinical characteristics were collected and echocardiography parameters wered measured. Results: mean age was 53.8 ± 13.5 years old, mainly men (70.6%), paroxysmal atrial fibrillation accounted for the majority (94.11%), the average duration of atrial fibrillation was 33.9 ± 33.3 months. The most common symptoms were palpitations (100%) and fatigue (70.6%), the severity of symptom was mostly grade 3 (58,8%). The majority of patients had cardiovascular risk factors (76.7%), the percentage of patients indicated for anticoagulation usage was 47.1%, whereas the percentage of patients taking anticoagulants was 32.4%. All patients had normal EF, diastolic dysfunction was seen in 82,4%. Conclusion: paroxysmal atrial fibrillation accounted for the majority, most patients had cardiovascular risk factors, the severity of symptom was mostly high grade, the number of patient taking anticoagulation was less than that as guided.
